DETERMINATION OF TITANIUM AND ZIRCONIUM IN ALUMINUM ALLOYS BY ATOMIC EMISSION SPECTROMETRY WITH INDUCTIVELY COUPLED PLASMA

A method is proposed for the determination of titanium and zirconium by inductively coupled plasma atomic emission spectrometry in aluminum alloys. Analytical lines of titanium and zirconium free from other elements significant spectral overlaps are selected. The selection of the sample preparation method was carried out, namely – dissolution in concentrated nitric acid. Studies of the metrological characteristics of the technique were carried out: for titanium and zirconium contents from 0.05 to 0.3 % of the mass. the accuracy index is no more than 5 % rel., which fully ensures the possibility of analytical control of the content of titanium and zirconium in products from aluminum alloys.
